Is that a fair assessment of Nietzsche, do you think?

greatcathy,
probably not. Then again Nietzsche was often read as engaged in attempt to overcome the metaphysical tradition. Heidegger is saying not so quick.

Rightly so. What Nietzsche critique of metaphsyics involved was a critique Platonism, its values and the post-Christian "enlightened" offshoots. One strand of Nietzsche (becoming, will to power, eternal recurrence etc) offered a different metaphysics.

What is contested is Heidegger's unifying interpretation of Nietzsche. Derrida, is saying, whoa. Not so fast Martin.

Is Heidegger's interpretation of Nietzsche
accurate and balanced? Is it fair?

Depends on what you reckon Heidegger was doing with his deconstruction of the Western metaphysical tradition.

I interpret him to be deconstructing the kind of calculative thinking that objectifies beings and transforms all forms of existence into resources to gain mastery over the earth.He is making explicit the metaphysical presuppositions of what Adorno called instrumental reason. Heidegger was trying to figure out what had gone wrong in the Western philosophical tradition.

Nietzsche's texts are read through that lens. It is common to argue that Heidegger mis read Nietzsche in his Nietzsche lectures from 1936 to 1943.
